ed lavandera in austin, texas, for us. thanks so much. among those watching the oprah interview, tyler hamilton, who rode with armstrong in three tour de france races and wrote the explosive book called "secret race" about doping inside armstrong's team. hamilton talked to cnn's piers morgan. listen. >> do you feel sorry for him? because he trashed you -- >> oh, yeah. we have a whole history -- >> he just kept trashing you saying it was all lies, you were trying to smear him. >> do i feel sorry for him? yes and no. yes because just watching him last night on tv, i haven't seen him since the last time he approached me in aspen about a year and a half ago. i haven't seen him since then. >> what did he say to you then? >> just some unkind words, that he was going to make my life a living hell both in the courtroom and out. that a federal investigation was going on. >> he was bullying you -- >> i was very angry for those -- for that encounter, for a long time. and scared for a while, too, because he's a powerful guy. i took those words seriou
